Injector Swap Update...
Ok, have had the 19#'ers in for a week now and either my computer funally adjusted, or my butt did. I couldn't really tell a difference at first, but now I'm noticing it doesn't take near the amount of pedal movement to get things moving. Definitely a nice increase in power, even tho I still can't get my 35's to bark. *grin*
Now if I could just get rid of that major hesitation off the line..... Tromping the throttle and having my truck fall flat on it's face for a second is kin of annoying.

Dawg, here's what I do to get rid of that hesitation:
Step 1. I pull the two air box/throttle body hoses off, hand rev the beast as high as I can, and squirt a can of "sensor safe" spray carburetor/fuel injector cleaner into the throttle body, which strips off the accumulation of gunk that's built up inside the dry flow intake tract. Use the whole can, maybe even two if you've not done this before. There will be a lot of thick bluish smoke coming out of the tailpipe, real scary and you'll **** off the neighbors.
What effect this cleaning has on the catalytic converter, I don't know, but it surely works.
Step 2. Remove the Idle Air Bypass valve body; leave the solenoid on the truck. Soak the valve body in some lacquer thinner, and clean inside it manually, with a toothbrush--there's a small double-head spring-loaded poppet valve and two seats in there--make sure to get them clean. Put it back together.
Step 3. Pull and sand the terminals inside the distributor cap, rotor tip also. There is a lot or arcing and corroding going on inside; get it all shiny smooth. I replace mine annually.
You'll be amazed how smooth and powerful the 4.9 is.

Thanks Eddie, I'll give that a shot. I'm really wanting to get a custom chip that will advance the timing correctly to get rid of the bogging totally, but I'm forcing myself to hold off until I get the cam and head work done. Would be kinda pointless before that then have to have it reprogrammed.

Hmmm. Yeah let us know if the TB cleaner does the trick. I don't have any problems with my truck since I installed the injectors. Like you said, one doesn't have to depress the accelerator as much as one used to to get moving. I noticed more upper rpm power and the engine doesn't work as hard as it used to when pulling a load. Also the engine just feels better in general, kinda like, "Now I have fuel I can do more work!",(my truck actually says this.... honest!) sort of feel. However I haven't been able to trace a miss I have at idle. This isn't related to the new injectors though.
